Tail stump spermatozoa: morphogenesis of the defect. An ultrastructural study of sperm and testicular biopsy

24 Apr 2009

Abstract excerpt

Summary We have studied the ultrastructure of testes biopsies and immotile spermatozoa from a supposed secondary infertile male. A wide range of tail defects has been described in testes and semen. Among these, tail stump spermatozoa occurs rarely. Although the origin of this defect is unknown, testes sections revealed that damage occurs during spermiogenesis at the latest stages during flagellum elongation in...
